Engineering Heterogeneous Nucleation during Solidification of Multiphase Cast Alloys: An Overview

Metals, 2023
The theory of heterogeneous nucleation was initially developed as a part of condensed matter physics, and later it was used as an important engineering tool to design metallurgical processes.

Single-bubble dynamics in nanopores: Transition between homogeneous and heterogeneous nucleation

Physical Review Research, 2020
When applying a voltage bias across a thin nanopore, localized Joule heating can lead to single-bubble nucleation, offering a unique platform for studying nanoscale bubble behavior, which is still poorly understood.

A New Atomistic Mechanism for Heterogeneous Nucleation in the Systems with Negative Lattice Misfit: Creating a 2D Template for Crystal Growth

Metals, 2021
Heterogeneous nucleation is a widespread phenomenon in both nature and technology. However, our current understanding is largely confined to the classical nucleation theory (CNT) postulated over a century ago, in which heterogeneous nucleation occurs ...

Grain Initiation and Grain Refinement: An Overview

Metals, 2022
Heterogeneous nucleation and grain initiation are two different processes in early-stage solidification (ESS), although both are deterministic. Heterogeneous nucleation refers to the formation of a 2-dimensional (2D) nucleus (a crystal plane of the solid)

Microstructural Stability of Ti based Composites Fabricated by Spark Plasma Sintering [PDF]

MATEC Web of Conferences, 2020
In our previous study, the effects of TiC heterogeneous nucleation site particles on formability and microstructure of additive manufactured (AMed) Ti-6Al-4V products were studied.

Nucleation mechanisms of equiaxed grains in the fusion zone of aluminum-lithium alloys by laser welding

Journal of Materials Research and Technology, 2021
The formation of different microstructures in aluminum-lithium alloys welding joints by laser welding has not been fully understood at the moment. In this study, the nucleation mechanisms of equiaxed grains in the fusion zone of aluminum-lithium alloys ...

Heterogeneous Nucleation and Grain Initiation on a Single Substrate

Metals, 2022
Recently, we have proposed a new framework for early stages solidification, in which heterogeneous nucleation and grain initiation have been treated as separate processes.

Effect of Heterogeneous Nucleation on Removal of Arsenic from Molten Steel by Rare Earth Addition

Metals, 2020
Cleanliness control is an eternal theme to improve the properties of steel products. With the increasing recycling rates of scrap steel, the removal and stabilization of residual elements have become a vital issue for improving the performance of steel ...

Molecular Dynamics Simulations on Effect of Surface Roughness of Amorphous Substrate on Nucleation in Liquid Al

Metals, 2022
In this study, we used molecular dynamics (MD) simulations to investigate the atomic ordering in the liquid aluminum (Al) adjacent to the amorphous substrate with smooth and rough surfaces.
